 I have a very strange DTS-CD decoding problem. The ffmpeg dts decoder
 produces strange distortions when decoding my "Engelsstaub - Anderswelt"
 DTS-CD. I ripped it flawlessly as *.dts.wav. When playing via external
 DTS-Decoder (S/P-DIF) everything is fine. But decoding it in software (via
 ffmpeg) produces distortions. There's a chance, that this CD is not
 properly mastered, but my external hardware decoder has no problems with
 it. When (re-)burned to a CD-R, my Bluray-Player also plays it flawlessly.
 So it should be also possible to decode it via ffmpeg properly.

 I have other DTS-CDs, which are perfectly decodable by ffmpeg. So at least
 my "workflow" seems to be correct. ;-)

 How to reproduce:
 {{{
 % ffmpeg -i input.dts.wav ... output.wav
 ffmpeg version 3.3.4
 built on amd64 / gentoo
 }}}

 I will upload the cue/dts.wav as anderswelt_dts_decoding_distortion.7z

 thanks!
